Source-derived summary

Petit Rouge is a red Italian wine grape variety that ampelographers believe is indigenous to the Valle d'Aosta (French: Vallée d'Aoste) region of northwest Italy. However, there is some confusion about whether Petit Rouge is the same variety as the red Swiss wine grape Rouge de Valais.

The grape is somewhat obscure and is not widely grown outside the Valle d'Aosta where it is primarily a blending variety but some varietal wines are produced. In blends, it adds floral aroma notes and dark color to the wines.

Wine regions

Petit Rouge is primarily found in the Valle d'Aosta region of northwest Italy between Piedmont and the Alps separating Italy from France and Switzerland. In general, altitude determines which varieties of grapes may be grown in a particular location, with reds growing at lower elevations and whites at higher elevations. However, despite its high altitude and mountainous location, nearly 90% of the wine in the Valle d'Aosta is red or rosé with Petit Rouge playing a considerable role in many of the blends produced under the Denominazione di Origine Controllata (DOC) designation of the region. This is because the variety thrives during the hot, dry months of the summer, allowing time to develop sufficient sugar levels and physiological ripeness.

DOC regulations

Within the Valle d'Aosta DOC, Petit Rouge must be harvested below a maximum yield of 12 tonnes/hectare and be fermented to a minimum alcohol level of 9.5%. Prior to release, the wines must be aged a minimum of 6 months which may include some time in oak.

Editorial summary

This brief starts where responsible research should: with the source description of “Petit Rouge” as italian grape variety. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 257-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The authority record carries competing date values—1970, 1970-05-25—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where Petit, Rouge and Italian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as italian grape variety. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 6, 2025. The linked authority identifier is Q2079799. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
